More Power and Better Combustion
Compared to factory coils, these units deliver over a 10% increase in power. The enhanced spark strength ensures a smoother idle, more consistent power delivery, and reduced risk of spark blowout. High-boost vehicles can also take advantage of wider spark plug gaps, contributing to more efficient and complete combustion.

Direct Fitment with Flexible Compatibility
Designed for seamless installation in EJ20 and EJ25 turbo applications, these coils are fully plug-and-play. For USDM EJ20 models with black coils, users can achieve compatibility by swapping coil boots and adjusting dwell settings in the tune.

Tuning Optional, Performance Guaranteed
Although no tuning is required, these coils offer benefits to tuners as well. Improved spark energy provides better timing control at higher RPMs, giving pro tuners more flexibility to optimize engine performance and extract additional power from the setup.
